2016 Democrats do the Iowa State fair….

Not since the Iowa steak fry last fall has Hillary Rodham Clinton faced such an important testing ground for retail politics and her affinity for fried food. On Friday, she will join her Democratic opponents, including Martin O’Malley, the former Maryland governor, and Senator Bernie Sanders of Vermont, to speak at the annual Wing Ding Dinner in Clear Lake, Iowa, an event that includes raising money for Democrats and raising cholesterol levels with chicken wings.

The event is just the start of Mrs. Clinton’s high-calorie swing through the state. On Saturday, she will join a dozen other presidential candidates at the Iowa State Fair in Des Moines, where the menu includes apple pie on a stick, deep fried nacho balls and pumpkin spice funnel cake.
